> Add utility methods to the SELF property
> ----------------------------------------
>
> Key: CAY-2759
> URL: https://issues.apache.org/jira/browse/CAY-2759
> Project: Cayenne
> Issue Type: Improvement
> Components: Core Library
> Reporter: Nikita Timofeev
> Assignee: Nikita Timofeev
> Priority: Major
> Fix For: 5.0.M1
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> After CAY-2754 is done we have SELF property generated for the entities.
> We could make it a separate type rather than {{EntityProperty}} and add some
> convenience methods to it.
> Here's what I already played with:
> {code}
> // query() method to create ObjectSelect
> List<Artist> artistList = Artist.SELF.query().select(context);
> // same with a where clause
> Artist artistById = Artist.SELF.query(Artist.SELF.eqId(1)).selectOne(context);
> // shortcut for a EXISTS/NOT EXISTS subquery
> long count =
> Artist.SELF.query(Painting.SELF.notExists(Painting.TO_ARTIST.eq(Artist.SELF.enclosing()))).selectCount(context);
> {code}
